Pressure Vessel Pole Cap Shock-Absorbing Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure vessels with plastic core containers lack an efficient and cost-effective method for integrating impact and shock protection during manufacturing, particularly at the pole caps, which can lead to unnecessary complexity and additional production steps.
Innovation Solution
The pressure vessel incorporates fiber-reinforced reinforcements that form shock-absorbing thickening in the pole cap areas during manufacturing, eliminating the need for additional plastic elements and enhancing the robustness by thickening the cylindrical wall, using thermoplastic or duroplastic resin systems with fibers like carbon, glass, aramid, or polyester, and arranging them at specific angles to provide comprehensive protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If additional plastic elements (foamed plastic elements) are incorporated into the outer casing for impact protection, then impact and shock protection is improved, but device complexity and manufacturing steps increase
Solution Approach 1:
The patent combines the impact protection function with the existing outer casing structure by integrating shock-absorbing reinforcement directly into the wound layers during normal manufacturing. This merges two previously separate functions (structural casing and impact protection) into a single integrated component, eliminating the need for additional plastic elements and reducing manufacturing complexity
Solution Approach 2:
The shock-absorbing reinforcement is incorporated into the outer casing during the initial manufacturing process rather than as a subsequent addition. The reinforcement thickening is formed during the winding process itself, performing the protective function in advance before the vessel is put into service
2Ease of manufacture
If shock-absorbing reinforcement thickening is formed during manufacture of wound layers, then manufacturing process is simplified, but structural complexity of the reinforcement increases
Solution Approach 1:
The patent applies shock-absorbing reinforcement thickening specifically in the pole cap areas where impact protection is most needed, rather than uniformly throughout the entire vessel. This localized approach provides enhanced protection at critical locations while maintaining simplicity in other areas, balancing structural complexity with manufacturing ease
3Object-affected harmful factors
If wound layers thicken from peripheral area towards end face, then impact protection at pole caps is improved, but material consumption increases
Solution Approach 1:
The reinforcement thickening is concentrated specifically in the pole cap areas through localized winding operations, rather than uniformly thickening the entire vessel wall. This ensures adequate material is applied where impact protection is critical while minimizing unnecessary material consumption in other areas
Solution Approach 2:
The patent applies reinforcement thickening selectively to the pole cap regions where it is most needed for impact protection, rather than applying uniform thickening across the entire vessel. This partial action approach provides sufficient protection at critical locations without the excessive material consumption that would result from comprehensive thickening
